V5 has been added. Along with:

• TriggerPrimitiveMaker can now generate the new TPs.
• TriggerActivityMaker, TriggerCandidateMaker, and TriggerAnaTree now have separate versions for V4 and V5.
• Some minimal configs that allow v5 to run correctly. But this is certainly not sufficient. @emanuele-villa if you can take a look at this that would be great, since you are the original person who prepared all the configurations.

This PR is certainly breaking, as it involves changes to the configuration files in order to correctly point to v4 or v5. Pinging @kwawrows , @alessandrothea here in case this impacts your studies:)
